The telecommunications industry within the sector of information and communication technology comprises all telecommunication/telephone companies and Internet service providers, and plays a crucial role in the evolution of mobile communications and the information society.
Telephone calls continue to be the industry's largest revenue generator, but due to advances in network technology, telecom today is less about voice and increasingly about text (messaging, email) and images (e.g. video streaming).High-speed Internet access for computer-based data applications such as broadband information services and interactive entertainment is pervasive. Digital subscriber line (DSL) is the main broadband telecom technology. The fastest growth comes from (value-added) services delivered over mobile networks.
